Directorate of public health (DPH) warns of heat risks, govt hospitals in Chennai begin prep work

Chennai: Amid rising temperatures in the city, the directorate of public health (DPH) has issued an advisory urging the public to take precautions against heat-related illnesses. Officials emphasised the importance of staying hydrated, avoiding midday heat, and recognising early symptoms that can signal conditions ranging from heat exhaustion to heatstroke. Govt hospitals have begun preparations to handle seasonal surges, ensuring adequate beds, essential medicines, and trained medical staff are available across public facilities. Health authorities have warned that if temperatures rise further — maximum temperatures deviating significantly from the normal or regularly exceeding 45°C — heat-related illnesses can range from mild conditions such as rashes and cramps to severe, life-threatening complications such as heatstroke. "To mitigate risks, health officials have been instructed to implement comprehensive heat action plans, conduct public awareness campaigns, and strengthen healthcare capacity," said director of public health Dr A Somasundaram. Public health facilities have been directed to ensure the availability of ORS packs, IV fluids, essential medicines, and cooling equipment, he said. Ambulances have been equipped and dedicated beds have been allocated across primary health centres, district hospitals, and medical college hospitals for managing heat-related ailments. The advisory also highlights the need for uninterrupted power supply to hospitals to maintain air-conditioning and cooling systems, alongside longer-term measures such as cool-roofing and improved ventilation. Surveillance of heat-related cases through designated health portals has been made mandatory to ensure timely reporting and response.Rajiv Gandhi Government General Hospital dean Dr K Shantaraman stressed the importance of preventive measures. "People should avoid stepping out during peak heat hours, stay well hydrated, and seek immediate medical care if they experience dizziness, high fever, or confusion, as early intervention can prevent complications," he said. The health department said that for mass gatherings and outdoor events, organisers must provide adequate drinking water, shaded areas, and medical support.
